very true. crower finally puts out a decent cam and cant get the correct lobe centers on them, fuck up the cam cards, and people wonder why their stage 3 280* duration cams sound smoother than stock, and are only pulling 5mmHG of vacuum. lol. worse part of that is jwt cam gears can only do 10* of adv/ret, and when your cams are out 13*, you're SOL.


the other large issue with the KA is that in 4 cylinders, the powerband is usually made higher in the RPM band, which the KA is not really known for being good at.

opening up the cams helps, but the intake manifold is then the bottle neck. once that is opened up, revving past 7500 requires a GOOD balanced rotating assembly, and some rotating mass weight shaving. fluidampers are $left testicle too.

n/a KA is fun, but after that certain initial limit, the power vs money is so out of whack its not worth it to try. but thats why im following some of these newer builds like PDM, greaser, scooter (the ITB guy who was turbo but went back to n/a recently with his haltech). they are getting alot more out of simpler setups with proper engineering, rather than trying to throw n/a bolt on parts at the KA and expect it to breathe like a vtec honda B series.

the key is to extract as much power with as little as possible, and the good tuning helps. this way, balancing out the power vs money ratio will prove that its not such a bad way to go.
